Synopsis: Sexual Hunter Riot

The Kirionira demons have found a way to infiltrate the human world through the dreams of men and women in another dimension. But humanity isn't helpless against them, as there are skilled hunters who tap into their sexual energy to combat the malicious forces. Riku Yoichi hails from a lineage of skilled hunters and boasts exceptional sexual power, making him a powerful adversary against the demons. He successfully defeats the demon king after leaving his hometown following middle school, thereby bringing the conflict to an end. However, his triumph comes at a cost - he loses his sexual potency in the process. Returning home, Yoichi discovers that the demon invasion remains despite his sacrifice. His former strength lost, he tries to enlist his childhood friend Namba Midori and her female classmates to help him regain his sexual drive, but they reject his advances.
